Abstract: 747,346. Windings for dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 2, 1953 [Nov. 4, 1952; Dec. 8, 1952], Nos. 27730/52 and 31065/52. Class 35. In a three-phase armature winding having concentric coils spread over 120 degrees for each phase band, the number of conductors in each coil side is proportional to the sine of the electrical angle by which it is displaced from the edge of the phase band. It is stated that although the M.M.F. per phase is not sinusoidal, when the coils of any two phases are connected in series, a sinusoidal M.M.F. results. To simplify end connections, the position of the edge of the phase band is preferably on the centre-line of a tooth or slot when there are an even number of slots per phase per pole-pair, and midway between the slot and tooth for odd numbers of slots per phase per pole-pair. The stator shown in Fig. 1 has 18 slots, the band edges being on the centre lines of teeth, i.e. the phase band of phase A comprises coils 12, 13, 14 and 15, 16, 17, lies between lines A2 and A3 at the centre lines of teeth 21, 22, the angle A20A3 being 120 degrees. The six slots within the band are thus spaced by 10 degrees, 30 degrees, 50 degrees, 50 degrees, 30 degrees and 10 degrees from the edge A2 or A3 of the band and the coils have numbers of conductors proportional to the sines of these angles. It is possible to design the winding so that each coil is fitted to its final position, there being no need to keep any coil side out of its slot until another is placed in position. Such an arrangement is shown in Fig. 2 for a 24 slot machine, the phases being shown by A, B and C and the coils in each phase band per pole by a, b, c and d, current directions being indicated. The coils are placed in position in descending order on the drawing.

Filed: 1971-06-15
Abstract: 1392447 Recording apparatus; measuring temperature electrically BERK PHARMA - CEUTICALS Ltd 9 June 1972 [15 June 1971] 27898/71 Headings G1J and GIN Apparatus for permanently recording day-today variations in the body temperature of an animal e.g. to detect ovulation comprises a housing 2 or 12 containing a chart recorder, and, rigidly mounted on the housing, a probe 1 or 11 containing temperature-sensitive means, e.g. a thermistor, thermocouple, or platinum resistance thermometer, and shaped for insertion in a body opening of the animal. Daily temperature readings are recorded as a succession of marks on a chart. In Fig. 1, a stylus carried by the needle of a galvanometer moves over a cylindrical chart visible through a window 3 in the housing 2. The galvanometer is in a high impedance signalling circuit powered by a cadmium sulphide cell. The circuit is energized when a push button 4 is pressed, and after allowing for the response time of the thermistor (e.g. 0À5 to 7 seconds) an outer button 5 is pressed to cause the stylus to mark or punch the chart in a position indicating the temperature. Release of the button 5 operates a ratchet to advance the chart one step, and release of the button 4 opens the circuit. In Figs. 2,3 a high-speed photographic film 14 is movable from a cassette 15 to a cassette 16 by a winder 17. A manually operable light-tight shutter 13 lies under part of a window 21 in the housing 12, and a second shutter (not shown) or a galvanometer needle or segment lies between the film and the shutter 13. In use, with the probe in a measuring position, pressing a button 24 opens the shutter 13 and energizes a measuring circuit which positions the second shutter so that the proportion of a transverse strip of the film exposed is a function of the measured temperature. As the film is wound on, a quick-acting developer is dispensed from a hollow coating roller 18 on to the exposed strip of the film so that a developed image representing the temperature becomes visible through the window 21. An adjustable resistor 23 in the measuring circuit allows the range of operation to be set. If ultraviolet light (from a filter or lamp) is used with a film forming a latent image on exposure thereto, the film may be developed by exposure to visible light.

Title: Improvements in or relating to tunnel furnaces for metallurgical uses
IPC: C22B1/20
Filed: 1922-10-20
Abstract: 195,590. Soc. Anon. J. Cockerill. March 30, 1922, [Convention date]. Tunnel furnaces; hearths.-In a tunnel furnace for metallurgical purposes the draught conditions are so adjusted that separate operations such as reduction, oxidation, fusion &c., can be carried out without substantial interaction between the different treatment zones. The furnace shown comprises three main zones, a preliminary-heating zone extending from the entrance end 6 of the tunnel to a burning-zone formed by one or more combustion chambers 21, and a cooling-zone extending from the burning-zone to the exit end. The cooling-zone is divided by a pair of dampers 24, 25 into two sections 22, 23, and through the latter the air for combustion is drawn by a fan 5 and supplied to the burners, which are inclined to deliver downwards on to the charge. The pressure of the air supply is such that the flame burns some distance from the burner nozzles. The charge is supported on perforated hearths 16 spaced from the trucks 12 and the heating-gases pass through the charge into the space between the hearths and the trucks. Between the dampers 24, 25 is a port 27 communicating with the atmosphere, and in operating the furnace the damper 24, and a further damper 26 in the preliminary-heating zone are so adjusted that atmospheric pressure is maintained in the burning-zone and the section 22 of the cooling-zone, thus re-' ducing to a minimum the flow of heating-gases along the tunnel between the dampers 24, 26. The burners may be controlled to produce oxidizing or reducing conditions in different sections of the burning-zone. At the exit end of the tunnel is an apertured door 7, which can be adjusted so that the air for cooling is drawn either through or over the charge. In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that the furnace may be used for the direct production of iron, the roasting, calcining, fritting and agglomeration of ores, the manufacture of cement, and the burning of bricks.

Abstract: 741,403. Mixing appliances. NAUTA, J. E. Oct. 16, 1953 [Oct. 18, 1952], No. 28628/53. Class 86. A method for grinding and mixing different materials, e.g. cereals consists in feeding alternately at least two mixers with amounts of the starting materials in the desired proportions; mixing said amounts in said mixers to a practically homogeneous mixture; feeding the whole of the contents of the mixer in which the mixture has obtained the desired homogeneous condition into grinding apparatus; feeding a continuous stream of material from the grinding apparatus into a final mixing plant wherein a considerable amount of ground material is collected and while so collected is mixed, and delivering the ground material mixed in the final mixing plant. In Fig. 1 unground starting materials from containers 1A, 1B, 1C, proportioned by weighing devices 2A, 2B, 2C, are fed into the mixer 8B whilst a charge already mixed in the mixer 8A is being fed into a hammer mill 14, and vice versa, the alternate charging and discharging of the mixers 8A, 8B being controlled by means of valves 7A, 12A, 12B. A continuous stream of ground material from the hammer mill 14 passes into a final mixer 16 having a discharge valve 17 which is controlled by means responsive to the level of material in the mixer 16 so that a continuous stream of mixed materials is discharged at such a rate as to maintain the level of materials in the mixer 16 near its upper end. The control means include a moving feeler 23 having an angle of tilt responsive to the level of material, connected to a valve in an oil pressure system, Fig. 2 (not shown), by which the valve 17 is raised or lowered. The feeler 23 may alternatively control electrically operated discharge means, such as a short conveyer screw, or may operate the switch of the driving motor of the mixer. In an alternative arrangement, Fig. 3 (not shown), three mixers are charged and discharged consecutively so as to feed a continuous stream of mixed materials into a pair of grinding machines from which a continuous stream of ground materials is pneumatically conveyed to a pair of final mixers, of which one receives and mixes the ground material whilst the other is being discharged, and vice versa. Specification 599,900 is referred to.
